Explanation:

To determine which organism does not have a cell wall, we recall the cell structure of each option:

• Animal cells (A): Lack a cell wall; they have only a cell membrane.
• Bacteria (B): Have a cell wall (e.g., peptidoglycan in most bacteria).

• Plant (D): Have a cell wall (composed of cellulose).

Thus, animal cells are the only ones without a cell wall.

Answer:

A. animal
